Less conventional oxidation states of the lanthanoids become important in complexes in which ligands such as trimethylsilyl‐substituted cyclooctatetraene anions or imidazol‐2‐ylidenes coordinate to the metal ion. These types of Ln n+ complexes ( n ≠ 3), which were still ignored ten years ago, may have sandwich or even oligodecker structures (see, for example, picture on the right) or contain carbene‐like η 1 ‐bound ligands.
